Un monstru cu procesor i9 gen12 și 64GB RAM... MORT din cauza unui singur cip ! 😱

In today's video, A monster with a 12th generation i9 processor and 64GB RAM... DEAD because of a single chip, we have a gaming "monster" to repair: an Acer Nitro 5 equipped with a 12th generation Intel i9 processor and no less than 64GB RAM. Although the specifications are top-notch, the laptop arrived on the workbench completely dead. Diagnosis: After measurements, we discovered an almost total short circuit on the main power line. The culprit? A QD9619A chip in the graphics card (GPU) power circuit. Solution: Since it is a specific chip and difficult to find quickly in stock, I turned to my "archive" of donor boards. I identified the chip on a parts board, carefully extracted it and replaced it on the Nitro's motherboard. Result: The laptop came back to life and is now working at maximum parameters! What you will see in this video: How to identify a short on the main line. Locating the faulty chip (QD9619A). The replacement process using parts from a donor board. Final testing of an i9 system with 64GB RAM.
